Breeding method of red glutinous rice

Abstract

The invention relates to a breeding method of red glutinous rice, which comprises the following steps: (1) performing hybridization of black glutinous rice with species of red-seed husk non-glutinous rice to obtain single-cross F0, planting to obtain single-cross F1 hybrids; (2) performing hybridization by taking high-yield white glutinous rice species of Gui No. D1 as a female parent, and taking single-cross F1 hybrids obtained by hybridization of Yulin black glutinous rice with red-seed husk non-glutinous rice species of Huanghongzhan as a male parent to obtain multiple-cross F0; (3) planting the multiple-cross F0 to gain F1 which all have black seed husk; planting the F1 to gain F2, separating the F2 to obtain plants with black, red or white seed husk, selecting plant seeds with red seed husk and glutinous endosperm for planting; performing selfing for 6-8 generations to obtain the required red glutinous rice species. The rice bred by the method of the invention has good glutinous property, good growing vigour during field growing, strong stems, red coarse rice, and comparable yield to current high-yield white glutinous rice.

Description

technical field [0001] The invention relates to a method for breeding crops, in particular to a method for breeding glutinous rice with red seed coat. Background technique [0002] Red glutinous rice has a higher content of protein, mineral elements and vitamins than ordinary glutinous rice, especially red glutinous rice contains manganese, zinc, copper, calcium, phosphorus, potassium, magnesium, iron, zinc and other inorganic salts are mostly higher than ordinary rice 1- 3 times, it also contains special ingredients such as vitamin C, chlorophyll, anthocyanin, β-carotene and cardiac glycosides that ordinary rice lacks, so it is more nutritious than ordinary glutinous rice, and has good diet and health effects. Red glutinous rice pigment is also a natural pigment, non-toxic, and maintains a variety of nutrients rich in plants, and can be used as a food coloring agent. [0003] At present, the main varieties of red glutinous rice are still the local varieties of the last cen...

AI Technical Summary

Problems solved by technology

[0003] At present, the main varieties of red glutinous rice are still the local varieties of the last century. The varieties are seriously degraded, the yield is low, the benefit is low, and the planting area is decreasing year by year, resulting in a shortage of supply in the market.
